In Rotherham, the average price guide for building projects like house extensions, loft conversions, and garage conversions varies significantly based on the scope and design.

### House Extensions Typically, a single-storey extension can cost between £1,200 and £2,000 per square metre. For a standard 20 square metre extension, you can expect to pay around £24,000 to £40,000.

### Loft Conversions Loft conversions tend to range from £30,000 to £50,000, depending on whether you are opting for a simple Velux conversion or a more complex dormer design. The average cost usually falls around £1,500 to £2,500 per square metre.

### Garage Conversions Converting a garage into a livable space typically costs between £8,000 and £15,000, depending on the existing structure and required modifications.

It's crucial to hire professionals who hold relevant certifications, such as NICEIC for electrical work or Gas Safe for any gas installations, ensuring the work is safe and compliant with local regulations.
